Natural fibers have gained attention in composite making since it is sustainable, renewable and environmental friendly. However, there are some drawbacks such as low tensile strength, modulus and flexural strength compared to industrial synthetic fibers. Various techniques have been used to increase the mechanical properties of the reinforced material in order to compete with synthetic fibers. This study is to produce reinforced fabric made from kenaf fibers woven into four different weave patterns. The reason for the use of different weave patterns is to reduce the crimp percentage as it may increase the tensile strength of the fabric. The weave patterns are Twill 4/4, Satin 8/3 and Basket 4/4, while Plain 1/1 is used as a benchmark for its tensile strength. The dry fabrics structure with different weave pattern was optimized using a simulation of WiseTex software. The dry fabrics were infused with unsaturated polyester to produce composite panel using vacuum infusion process. The dry fabric and the composites were tested on tensile strength and compared with the Plain 1/1 weave pattern. The result shows the breaking strength of dry fabric increased when different weave pattern with low crimp percentage were used compared with Plain 1/1. Yet, in composite form there is reduction in tensile strength for Basket 4/4 due to changes in the fabric structure making some parts of the composite became weaker. The other weave patterns still retain the trend of increment in tensile strength compared with Plain 1/1 weave.
